The article contains the following contents:
In the present work, a type of biochar materials derived from carbonizing peanut shells were obtained and employed as the adsorbents of pipet-tip solid-phase extraction (PT-SPE) for the enrichment and determination of six endocrine-disrupting phenols (EDPs) in combination with high-performance liquid chromatog. equipped with UV detector (HPLC-UV). Abundant aliphatic and aromatic carbon structures and functional groups from polar heteroatoms (N, O, S) were distributed in the low-cost and eco-friendly peanut shells-derived biochar materials and were favorable for the enrichment of target EDPs. Moreover, the theor. calculation based on d. functional theory (DFT) proved that the effective enrichment of EDPs in aqueous samples benefited from the effective adsorption on the peanut shells-derived biochar materials. The exptl. factors influencing the extraction efficiency were investigated, including adsorbent amount, aspirating/dispensing cycles, the type of elution solvent and elution times, salt addition, sample solution pH and type and volume of washing solvent. Under the optimal conditions, the proposed PT-SPE method exhibited good linear relationship (R2 > 0.993) in the range of 0.5-400μg/L and low limits of detections (LODs) from 0.25 to 2.5μg/L, as well as good precision and accuracy with relative standard deviations (RSDs) of 0.3%-13.2% and recoveries of 83.5%-117.1%. Finally, the biochars-based miniaturized pretreatment method was employed for the determination of six EDPs in bottled water, milk, tea beverage and disposal plastic bag soaked solution with recoveries from 77.5% to 116.5%. The experimental procedure involved many compounds, such as 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .
4-(2-Phenylpropan-2-yl)phenol(cas:599-64-4) is a natural product found in Panax ginseng.Computed Properties of C15H16O 4-(2-Phenylpropan-2-yl)phenol is a useful reagent for preparing and characterizing aromatic polyphosphonates as high refractive index polymers.
